Radio-Shack has a new version of their 49 MHz walkie-talkie that uses a
combined earplug/mic, the kind that picks up your voice *out* through your
ear. The actual transceiver is in a little box that mounts on a belt clip.
The wire between is also the antenna.

These things are not particularly cheap -- ~$80/pair -- but work fairly
well at free-space ranges up to 1/4 mile. Sould be ideal for a bike.

If carefully you pick the channel number (A, B, etc.) printed on the box
to be "A", it will interoperate with both of the older-styles: "bug ears"
(like a telephone operators headset with a whip and a wire to a belt box),
and the small hand-held box-with-shorty-whip style.
